JOSEPH F. OH'MELIR, OF ST. LOUIS, MISSOURI.

, VENTlLATlNG-WINDOW.

SPECIFICATION forming part of Letters Patent No. 791,248, dated May 30, 1905.

Application filed March 11, 1.905. Serial No. 249,570.

To all whom, it may concern;

Be it known that I, J osnri-I F. (h-IMELIR, a citizen of the United States, residing in the city of St. Louis. in the State of Missouri, have invented certain new and useful improvements in Ventilating-Windows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

. My invention relates to that class of ventilating-windows. used in churches and other similar buildings-and in which are used outer storm-panes and inner panes usually of cathedral-glass that are protected by the stormpanes.

Figure I is an elevation of my improved window looking at t e outer sir.le thereof. Fig. IT is a vertical section taken through my window set in the window-frame ofa building. Fig. III is an enlarged. view of parts of the windbw at the point of pivotal attachment of the pane-casement to its supporting-frame. Fig. IV a perspectii e view of a fragment of the pains-casement at the location of one of its pivotifs. Fig. V is a perspective view of one of tlie lower corners of my window.

1 designates the supporting-frame of my \vindow, wliich is of rectangularshape and formed entirely of angle-iron without any joints being present between the corners of the frame eit ier at its sides or at its top or bottom. At the o hter side of thesupporting-frame is div-extending flange 2, that extends continuously across the top of the frame and downwardly therefrom at eaeh'side to points at approximately the vertical center of the frame, as seen in Figs. 1 and II. At'the inner side of the frame is a flange 3, that extends eontinuously across the bottom of the frame {and upwardly therefrom at each side to points approximately at the vertical center of the frame. (See Figs. II and V.) Midway of the height of the supporting-frame 1 are pivotj'stud slots 4, that are located between the lower ends of the flanges 2 and the upper ends/of the flanges 3. (See Fig. III.) The supporting-frame l is adapted to be mounted in a Window-frame A, as seen in Fig. ll, and itis' surmounted by a channel-shaped retaining-strip 5,. that is secured to the top of the supporting-frame and enters into the windowframe A. The supporting-frame may be secured at the bottom to the window-frame by any suitable means, such as screws 6.

B designates a rectangular casement that is constructed of angle-iron and-which is swingingly supported within the supporting-frame 1 by pivot-studs 7, projecting from the sides of the easement and seated in the notches din the supporting-frame sides. The, casement B consists of a-continuous main flange 8, by which the studs 7 are carried and which fits immediately within the snpporting-frame l, and an inwardly-extending continuous flange 8, vlocated at the inner side of the easement. (See Figs. LII, IV, and V.)

Cdesignates a rectangular detachable stop of angle shape in cross-section and consisting of a flange 9. fitting against the easementflange 8, and a flange l0, projecting inwardly within the easement, said last-named flange being located at the outer side of the stop- The stop O is, located remote from the inwardly-extending flange 8 of the easement B,

and it is secured to the easement bybolts 11 located at intervals and passing through said members. v

12 designates an inner pane of glass set into the easement B and resting against its inwardly-extending flange 8', said inner pane being preferably surrounded by a rectangular metallic rim 1'3. This-inner pane is held within the casement due to its resting against the casement-flange 8' andthe hearing of the stop C thereagainst. I

14 designates an outer or storm pane of glass set into the easement and resting against the I inwardly-extending flange 10 of the detachable stop 0. This outer pane is held Within the easement against said stop-flange by a layer 15 of putty.

When the panes 12 and 14 are to be set into the easement B, the stop O is removed from the easement by withdrawing the bolts 11, so that said stop may be lifted from the casement. The inner plane 12 is then set in place against the casement-flange 8' and the stopC is again introduced and secured by ,the bolts 11. The outer pane 14 is then seated in the'I casement to rest against the stop-flange 10 and is secured by the application of the layer of putty at the 'joint between the easement and the edges of said pane. Thus a very secure means of mounting of the inner and outer panes is attained. It will be seen that the panes 12 and 14 may both be readily extracted from the easement at any time, as only the single layer of putty needs to be removed, when the outer pane 14' may be lifted from the easement, and thereafter it is only neoes sary to withdraw the bolts 11 p to extract the stop in order to permit the removal of the inner pane 12.

For the purpose of avoiding breakage of the panes of glass in the easement I apply to the supporting-frame flanges 2 and 3 a bumper-. strip 16, (see Figs. II and V,) against which the casement O strikes when it is swunginto closed position.

17 represents hoods or rain-guards secured to the sides of the supporting-frame l at the outer edges thereof and at the points of pivotal support of the easement in said frame, these guards being designed to prevent the beating of rain through the joints at the points of pivotal support of the casement.

I'claim as my invention 1. In a ventilating-window,the combination of a rectangular supporting-frame, a rectangular casement swingingly mounted in said frame and provided at its inner side with an inwardly-extending flange, an inner pane seated in said casement and resting against said inwardly-extending flange, a rectangular detachable stop seated in said casement, and an outer pane resting against said stop, substantially as set forth.

2. In a ventilating-window,the combination of a rectangularsupporting-frame, a rectangular casement swingingly mounted in said frame and provided at its inner, side with an inwardly-extending flange, an inner pane seated in said casement and resting against said inwardly-extending flange, a rectangular detachable stop seated in said casement, and

an outer pane resting against said stop; said stop consisting of a flange fitting against said casement and a flange extending inwardly therefrom at the back of said outer pane, sub stantially as set forth.

3. In a ventilating-window,the combination of a rectangular supporting-frame, a rectangular casement swingingly' supported in said frame and consisting of a main flange and an inwardly extending flange, an inner pane restingagainstsaidinwardly-extendingflange,

a rectangular stop fitting within said casement against its main flange, bolts detachably securing said stop to said casement and an outer pane resting. against said stop, substantially as set forth.
